The lanthanum cerium in the fiber is formed by calcination of the electrospinning fibers of polymer/inorganic composite at 600 °C and a polycrystalline hollow fiber with diameter of 1∼5 μm can be obtained at 1000 °C for 12 h. After calcination at 1400 °C, the lanthanum cerium grains are closely connected to each other with clear grain boundaries and the hollow structure can be observed in the cross‐section of the fiber.
